The most incredible advancement in our history, we launch the Blink BL100/BL300 combo pack. Since 2009 Blink has been a power sports leader in advanced Bluetooth power sports integration. This device is a completely self contained system with boom microphone that allows for full A2DP Bluetooth 4. 0 communication. The device has no parts that need to be mounted outside the helmet. The rechargeable batteries and circuit board are integrated into the back of the speaker housing, and override controls are mounted on the boom microphone. The external BL300 remote control puts the controls on the bar, next to the clutch, allowing for full thumb control without having to remove the thumb from the bar.
